Claims.

This invention relates to plumbing fixtures and particularly to a watersupply fitting therefor.

An object of the present invention is the pro- 5 vision of a novel watersupply fitting for tubs, bowls, sinks, lavatories, and the like throughwhich the same may be rapidly supplied with water no-iselessly andwithout splash.

Other more specific objects and advantages will appear from thefollowing description of two illustrative embodiments of the presentinvention.

In the accompanying drawings:--

Figure 1 is a side elevation, partly in section,

of a porcelain bowl equipped with an integral water supply fittingembodying the present invention.

Fig. 2 is a sectional detail, on a larger scale, of the supply fittingshown in Fig. 1.

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2.

Fig. 4 is a front elevation of the supply fitting of Fig. 2. 1

Fig. 5 is a side elevation, partly in section, of an enameled metal bathtub equipped with a modified form of supply fitting embodying thisinvention.

Fig. 6 is a sectional detail, on a larger scale, of the supply fittingshown in Fig. 5.

Fig. 7 is a rear elevation of the fitting shown in Fig. 6.

Fig. 8 is a View similar to Fig. '7 with the attaching plate removed.

The porcelain bowl shown at 10 in Fig. 1 is equipped with an integralwater supply fitting comprising a horizontally extended chamber 11formed within the rear wall thereof. The forward wall 12 of the chamberterminates along its lower edge in a depending lip 13 which is 4.9spaced slightly from the rear surface 14 of the bowl to form ahorizontally extended narrow outlet 15 through which water from thechamber 11 is discharged in a relatively thin sheet-like stream incontact with and along the surface 14 of the bowl. The rear surface ofthe lip 13 is preferably curved, as indicated at 16.

A narrow balile -17, projecting from the forward wall 12, extends thefull length of the chamber 11 and divides the same into upper and lowercommunicating compartments 18 and 19. The top face 20 of the battle ispreferably inclined downwardly, as indicated, and terminates in a narrowedge 21 directed toward the rear wall 22 of the chamber.

A water supply channel 23 penetrates the rear wall 22 of the chamberintermediate the ends thereof, preferably above the baffle 17, so thatthe incoming stream is directed substantially horizontally into theupper compartment 18, and

so that the force of the stream is expended against the forward wall ofthat compartment above the bafile 17. Thereafter, the stream spreads inopposite directions lengthwise of the compartment 18, filling the same,and ultimately fiowing in a wide fiat stream and at a lower velocityinto and through the relatively shallow lower compartment 19, fromwhence it emerges through the narrow outlet 15 onto the rear surface 14of the bowl.

The inlet end of the channel 23 is preferably enlarged to form a socket24 adapted to receive the end of a valve controlled supply pipe (notshown) suitable compressible packing being employed in the socket toform a watertight joint with the pipe.

The enameled metal bath tub 10' shown in Fig. 5 is equipped with a watersupply fitting which is similar in many respects to the fitting abovedescribed. It includes a horizontally extended chamber 11" which isdivided into upper and lower elongated communicating compartments 18'and 19 by a baffie 17' which extends the full length of the chamber andprojects rearwardly from the forward wall thereof. A curved lip 16spaced from the rear surface 14' of the tub provides a narrowhorizontally extended outlet 15' for the lower compartment 19, anddirects the discharge therefrom onto the surface 14'. The waterdischarges in a fiat stream onto the surface 14 and fiows downwardlythereon.

In this instance the rear of the chamber 11 is closed by a removablecover plate 22', secured thereto by appropriate means such as screws 25which enter attaching lugs 26 formed in the chamber. Suitable packingmaterial 27 is interposed between the plate 22' and its seat 28 to forma watertight joint.

A hollow boss 29, formed integral with the plate 22, contains a channel23 through which water is directed substantially horizontally into theupper compartment 18' of the chamber above the baille 17. The lower end24' of the channel is internally threaded or otherwise fashioned forconnection with a valve controlled water supply pipe. (Not shown). Theaction of the water ithin the upper and lower compartments 18' and 19'is substantially the same as that hereinabove described in connectionwith the compartments 18 and 19 of the other fitting, and the waterultimately discharges noiselessly through the out- 9' let 15' in a widefiat stream which follows the inner surface 14' of the tub withoutsplashing.

It will be noted that before applying the cover plate 2.2 to its seat28, the interior of the metal chamber 11' is accessible, so that thesame may be readily painted to prevent rust.

Various changes may be made in either of the embodiments of theinvention hereinabove specifically described without departing from orsacrificing the advantages of the invention as defined in the appendedclaims.

We claim:-

1. In a plumbing fixture the combination of a receptacle having anupright wall, and means for supplying water to said receptaclecomprising a horizontally extended chamber, a baffle projecting from onewall of said chamber and extending lengthwise thereof to divide the sameinto upper and lower communicating compartments, means for dischargingwater into said upper compartment through the opposite wall of saidchamber, said lower compartment being open to said receptacle, and ahorizontal lip extending lengthwise of said lower compartment and spacedfrom said wall to deflect the water discharged from said lowercompartment and to direct the same in a fiat, wide stream against saidwall.

2. In a plumbing fixture the combination of a receptacle having anupright wall, and means for supplying water to said receptaclecomprising a horizontally extended chamber having a discharge opening atone side of the bottom thereof substantially coextensive with the lengthof said chamber, a horizontally extended lip covering said opening andspaced from said wall to direct the discharge from said chamber againstsaid wall, a supply channel penetrating the other side of said chamber,and a horizontally extended baflie interposed between said supplychannel and said discharge opening to dissipate the force of the liquidstream supplied through said channel before the liquid reaches saiddischarge opening.

3. In a plumbing fixture the combination of a receptacle having anupright wall, and means for supplying water to said receptaclecomprising a horizontally extended chamber having a horizontal outletsubstantially coextensive with the length of said chamber at one side ofthe bottom thereof, a horizontally extended lip covering said outlet andspaced from said wall to direct the discharge from said outlet againstsaid wall, a horizontally extended baffle in said chamber above saidoutlet, said bafiie having an upper surface inclined downwardly towardthe opposite side of said chamber, and a channel penetrating saidopposite side of said chamber above said bafiie for directing a streamof water thereinto.

4. In a plumbing fixture the combination of a receptacle having anupright wall, and means for supplying water to said receptaclecomprising a horizontally extended chamber having a bottom outletadjacent said wall, said outlet extending horizontally and substantiallycoextensive with the length of said chamber, a horizontally extended lipcovering said outlet and spaced from said wall to direct the dischargefrom said outlet against said wall, a plate removably attached tosaidchamber to close one side thereof, a water supply channelpenetrating said plate, and a baiile within said chamber effective tobreak the force of the water stream admitted through said channel sothat said water passes at lower velocity through said outlet.

5. In a plumbing fixture the combination of a receptacle having anupright wall, and means for supplying water to said receptaclecomprising a horizontally extended chamber having a horizontallyextended outlet at one side and adjacent the bottom thereof, ahorizontal lip covering said outlet and effective to direct thedischarge from said outlet against said wall, a relatively narrow supplychannel penetrating the other side of said chamber, and means withinsaid chamber for receiving the impact of the stream of water admittedthrough said channel and for spreading the same longitudinally of saidchamber prior to reaching said outlet.
